MX25V4006EZUI-13G

Memory IC Overview

The MX25V4006EZUI-13G is a 4-Mbit CMOS Serial Flash Memory from Macronix, operating on a single 2.35V to 3.6V supply. It features a 4-wire SPI interface supporting Mode 0 and Mode 3 with a maximum serial clock of 75MHz. The memory organization consists of 128 equal sectors (4KB each) and 8 equal blocks (64KB each). It supports Dual Output read mode at up to 70MHz. Key electrical parameters include a maximum active read current of 12mA at 75MHz and a standby current of 15µA. The device guarantees 100,000 erase/program cycles and 20 years data retention.

Memory IC Feature Summary

• Supports Serial Peripheral Interface (SPI) Mode 0 and Mode 3 with dual output capability for enhanced read throughput.
• Includes hardware and software protection mechanisms via the WP# pin and status register bits to prevent inadvertent erasure or programming.
• Features an internal auto program and auto erase algorithm that manages timing and verification without host CPU intervention.

Memory IC Applications

• Code storage in embedded systems requiring direct execution from flash.
• Data logging applications utilizing sector-level erase capabilities.
• Firmware storage in consumer electronics and industrial controllers.

Memory IC Procurement Notes

Verify the specific package variant, as the 'ZUI' suffix denotes the 8-USON (2x3mm) package. Confirm the temperature grade matches the application requirements, as the datasheet specifies operation from -40°C to +85°C. Ensure the ordering suffix aligns with the required tape and reel quantity if applicable. Cross-reference the full part number with the manufacturer's latest documentation to confirm current production status and any potential obsolescence notices.

Memory IC Selection Notes

Select this component when a small footprint is required due to the compact 8-USON package. It is suitable for designs needing low power consumption during standby and deep power-down modes. The device is appropriate for applications requiring robust data protection against accidental writes. Consider the 75MHz clock speed for high-performance code execution needs within the specified voltage range.

Memory IC Part Context

This part belongs to the MX25V series of 2.5V Serial NOR Flash memories. It shares architectural similarities with other Macronix devices but is distinguished by its specific voltage range and package options. The MX25V series is designed for cost-sensitive applications requiring reliable non-volatile storage with standard SPI compatibility.

Memory IC FAQ

How does the HOLD feature function?

The HOLD# pin allows pausing serial communications without deselecting the device. Communication resumes when HOLD# goes high while SCLK is low. This feature does not interrupt ongoing program or erase operations.

What is the purpose of the WREN command?

The Write Enable (WREN) command sets the Write Enable Latch (WEL) bit. This latch must be set before executing any commands that modify the device content, such as Page Program, Sector Erase, or Write Status Register.
